2012 c63 primary cat delete
Hey guys got a 2012 c63 just did secondary cat and resonators delete and still not too happy with how quite it is . Considering removing the primary cat at this point. Did anybody have any suggestions on o2 sensor spacers that will turn off the check engine light off??

Sorry, but I just had to say that, but as others have said, from the outside it must be very noisy and probably attracts too much negative attention

Removing the resonator was a mistake as they lose the amg tone without it.
Best set up is either of the below.
- Secondary cat delete only, rest stock
OR
- Headers (cats or without), secondary cat delete rest stock.
Every C63 I have heard with the resonator or mufflers messed with sound awful.

Stand outside your car and have a friend rev it....you will sh*t yourself (I've tested, scared the hell out of me). Then have them do a flyby, I bet it's loud. If you don't have any friends (no worries), find a tunnel, underpass, parking garage or back your car up to a wall/building and give it some revs. As others stated, lowering back seats are a must.
